Complications et atteintes systémiques de la polyarthrite rhumatoïde [Complications and systemic manifestations of rheumatoid arthritis].

Rheumatoid arthritis (RA), in addition to the traditional joint damage can affect all organs as a systemic disease. Extra-articular manifestations of RA are highly variable ranging from rheumatoid nodules (most common) to rheumatoid vasculitis presenting a significant morbidity and mortality (49% at 5 years). With the new algorithms of treatment (earlier) and the use of biologics, the incidence of severe extra-articular manifestations decreases. Regarding the treatment of rheumatoid vasculitis, rituximab looks promising. RA also increases cardiovascular risk and the risk of osteoporosis. It is therefore important to identify these risks and, if appropriate, treat them. Collaboration with the general practitioner is essential in this situation.

Extraintestinal manifestations in inflammatory bowel disease: frequency and associated risk factors in the nationwide Swiss IBD cohort study (SIBDCS)

Background: Data on the frequency of extraintestinal manifestations (EIM) in Crohnʼs disease (CD) and ulcerative colitis (UC) are scarce. Goal: to evaluate prevalences, forms of EIM and risk factors in a large nationwide IBD cohort. Methods: Data from validated physician enrolment questionnaires of the adult Swiss IBD cohort were analyzed. Logistic regression models were used to identify EIM risk factors. Results: 950 patients were included, 580 (61%) with CD (mean age 43yrs) and 370 (39%) with UC (mean age 49yrs), of these, 249 (43%) of CD and 113 (31%) of UC patients had one to 5 EIM. The following EIM were found: arthritis (CD 33%, UC 21%), aphthous stomatitis (CD 10%, UC 4%), uveitis (CD 6%, UC 4%), erythema nodosum (CD 6%, UC 3%), ankylosing spondylitis (CD 6%, UC 2%), psoriasis (CD 2%, UC 1%), pyoderma gangrenosum (CD and UC each 2%), primary sclerosing cholangitis (CD 1%, UC 4%). Logistic regression in CD identified the following items as risk factors for ongoing EIM: active disease (OR 1.95, 95% CI 1.17-3.23, P=0.01), positive IBD family history (OR 1.77, 95% CI 1.07-2.92, P=0.025). No risk factors were identified in UC patients. Conclusions: EIM are a frequent problem in CD and UC patients. Active disease and positive IBD family history are associated with ongoing EIM in CD patients. Identification of EIM prevalence and associated risk factors may result in increased awareness for this problem and thereby facilitate their diagnosis and management.

Interventions hybrides et malformations cardiaques congénitales [Hybrid procedures in congenital heart disease]

La complexité croissante de la prise en charge des malformations cardiaques congénitales impose des interventions chirurgicales et des cathétérismes cardiaques interventionnels fréquents. Chacune de ces techniques a ces limitations propres. Les interventions hybrides associent les avantages de la chirurgie cardiaque et du cathétérisme interventionnel. Dans notre expérience, les thérapies hybrides permettent de diminuer le temps de circulation extracorporelle, de diminuer la morbidité des interventions chirurgicales, de raccourcir le séjour du patient aux soins intensifs. Pour certaines malformations cardiaques congénitales complexes pour lesquelles il n'existe pas de chirurgie ou de thérapie interventionnelle idéale, les interventions hybrides sont en train de s'imposer comme la prise en charge incontournable. Increasing complexity in management of congenital heart disease imposes more frequent surgeries and interventions. Each technique has its own limitations, which could impair the anticipated result. Hybrid procedures join the advantages of cardiac surgery and interventions, creating a synergy in the management of these patients with cardiac anomalies. In our experience, hybrid procedures shorten cardiopulmonary bypass, reduce morbidity of surgery and reduce duration of stay in the intensive care unit. For some complex congenital heart diseases for which there are no ideal surgical or interventional options, hybrid procedures are becoming increasingly important in their management. Finally hybrid procedures allow surgeons and cardiologist to achieve complex procedures that could not be possible in another way

Le xeroderma pigmentosum et ses manifestations oculaires. A propos du premier cas camerounais [Xeroderma pigmentosum and its ocular manifestations. The first case in Cameroon].

We report a case of xeroderma pigmentosum in a 9-year-old back Cameroonian boy. The diagnosis was based on typical clinical presentation of the disease: cutaneous atrophy, hypepigmented macules, and areas of depigmentation on sun exposed regions of the skin. Multiple tumoral lesions were localized on the head. Ocular findings were also present: conjunctival hyperemia, peripheral corneal opacification. Excision of the tumors and potoprotection was proposed for this patient. The role of tribal black African marriage traditions in disease transmission is discussed.

Extraintestinal manifestations of Crohn's disease.

In each case of extraintestinal manifestations of Crohn's disease, active disease, if present, should be treated to induce remission, which may positively influence the course of most concomitant extraintestinal manifestations. For some extraintestinal manifestations, however, a specific treatment should be introduced. This latter part of disease management will be discussed in this chapter, in particular for pyoderma gangrenosum, uveitis, spondylarthropathy--axial arthropathy--and primarysclerosing cholangitis, which have also been described in quiescent Crohn's disease. Few new drugs for the treatment of extraintestinal manifestations of Crohn's disease have been developed in the past and only the role of infliximab has increased in Crohn's disease-related extraintestinal manifestations. Drugs specifically aimed at this treatment, stemming from a few randomized controlled studies or case series, are sulfasalazine, 5-ASA, corticosteroids, azathioprine or 6-mercaptopurine, methotrexate, infliximab, dapsone and cyclosporine or tacrolimus.

Lésions buccales du reflux gastro-oesophagien de l'enfant: des réalités et quelques mythes [An interface between pediatrics and oral medicine: oral manifestations of gastroesophageal reflux in children]

Gastro-oesophageal reflux (GOR) is a common disorder in the pediatric population. In association with esophagitis, GOR may impair children's quality of life. Extra-oesophageal manifestations are of specific interest in oral medicine because the refluxate may reach impair both oral mucosa and hard dental tissues. Some oral symptoms are so specific that they should raise the attention for other GOR symptoms. Dental erosion is a potential risk in children with gastroesophageal reflux: the pediatrician should routinely refer children with gastroesophageal reflux to a pediatric dentist to diagnose erosions and if needed restore the teeth. Conversely, in the presence of unexplained dental erosions the dentist and/or the pediatrician should discuss the possibility of an occult GOR.
